Preheat oven to 350 degrees. Blend cream cheese, butter, and green onion. Mix in cooked chicken and ham. Grease a large cookie sheet. Unfold crescent rolls and press edges of two rolls together to make a large rectangle (4 per package). Scoop 1/2 cup of mixture in the middle of the rectangle. Gather up the edges towards the top and twist, pinching any openings together. Brush a little melted butter on the tops. Then, sprinkle bread crumbs on top. Bake for 25 minutes. Delicious!!!
